Craft Advantage
In any refrigeration process or application the heat being transferred can cause condensation to form on the evaporator. If the temperature is low enough the gathered condensation will freeze, leaving a frost deposit on the evaporator. The frost will subsequently act as insulation on the evaporator pipes and reduce the efficiency of heat transfer, which in turn means the system needs to work harder to cool the environment sufficiently, or that the fridge cannot reach the setpoint at all.
This has repercussions on either the product not being kept or cooled to the correct temperature, which can increase instances of faulty product, or it means more energy is expended trying to maintain the correct temperature, increasing running costs. In either case there is a loss to the business due to wastage or higher overheads.
Defrost thermostats combat this by periodically melting any frost forming on the evaporator and allowing the water to drain away, keeping the moisture level in the environment as low as possible.
